CHURN.

SPECIFICATION forming part of Letters Patent No. 530,531, dated December 11, 1894.

Application filed April 14, 1894.

To all whom, it may concern.'

Be it known that I, JAMES MARON JACK- SON, a citizen of the United States, residing at Millport, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to churns and has particular reference to that type of such machines in which the dasher is mounted on a horizontal axis and Within a drum-shaped or cylindrical casing.

rIhe object of my invention is to provide means whereby wear of the bearings can be taken up and yet permit no escape of the cream at such bearings; and a further object of my invention is to provide a light, simple and economically constructed churn.

To these ends my invention consists in the construction and combination 4of parts as hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of the churn. Fig. 2 is a section on line 2-2 of Fig. l. Fig. 3 is a detail perspective of a portion of the dasher frame. Fig. t is a detail section illustrating a modification hereinafter referred to.

Similar reference letters indicate the same parts in the several views.

The cylindrical or drum-shaped casing a is mounted on a suitable base a; and secured in the center of one of the heads c2 is a screwthreaded bushing b, through which extends the screw b having its inner end preferably rounded as shown. A set nut b2 is employed to hold the screw in its adjusted position and a washer b3 is interposed between the said nut and the flange of the bushing to make this bearing liquid tight. The other head a of the casing has centrally7 secured therein an inwardly flaring cone-shaped thimble or bearing c in which is fitted the cone plug c having a screw-threaded stud at its outer end uand a square stud c2 at its inner Serial No. 507,546. (No model.)

be slipped into the ends of the arms and there held by one or more pins c3, preferably of wood. One of the side pieces e is provided at its middle with a concaved socket piece f to receive the end of screw b', and the other side piece is provided with a square socket f to receive the square stud c2 of the plug c so that the dashers may be operated by the handle (l.

To take up wear of the bearings, the nut b2.

is loosened, the screw b turned to cause the dasher frame to press the cone-plug well into its bearing c. and the nut again tightened.

The close Iit of the plug and bearing prevents rattling or leakage at that end of the casing, while at the other end, the concaved socket f prevents rattling and the washer b3 prevents leakage.

The screw b and socket f may be of wood, and the socket f and plug c may also be of wood, thus avoiding the use of any metal in the churn. In this case the thimble c is dispensed with, as indicated in Fig. 4, and the conical bearing in the casing elongated by securing on the outside thereof ablock C10.

The opening of the casing at the top is provided with a funnel shaped mouth g in which the square cover g having beveled sides g2 fits.

Owing tothe dashers being at the ends only of the frame, when the cream has been agitated suiiciently to produce the granules of butter, the lower dasher can be reciprocated back and forth in the mass (the upperone being above the surface) and so gather the butter.

Having now described my invention, what I claim is- 1. A churn comprising in its construction a casing having a fixed cone-shaped bearing at one end and a screw at the other end, a cone-plug fitted in said bearing whereby a tight joint is formed between the casing and the cone-plug, and a dasher frame mounted 5 on said screw and cone-plug, substantially as described.

2. A churn comprising in its construction the casing having the screw b nut b2 and 'washer b3 at one end, and the hollow cone c ro at the other end, the cone-plug o' having a JAMES MARION JACKSON.
